Recent advances in complementary metal oxide semiconductor (CMOS) technology have led to sensors with pixel sizes on the order of a micron, which greatly increases spatial crosstalk. This work develops the fundamental limitations of DoFP polarimeters due to noise and expands upon how spatial crosstalk affects the reconstruction of the Stokes parameters.
